T0 at whom it may concern;

Be it known that I, MILTON F. WILLIAMS, a' citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Cages for Crushers and Pulverizers, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which Figure 1 is a sectional view through acrusher or pulverizer in which my improved cage is mounted. Figs. 2, 3,and 4 are detail sectional views showing the adjusted position of thecage-bars, and Fig. 5 is a fragmentary pers ective'view of the cage-barterminals.

T 's invention relates to a new and useful improvement in cages forcrushers and pul verizers.

One of the objects of the invention is to construct a cage so that theparts thereof will occupy a small space in shipping and also to providering-mounts of various sizes for the cage-bars, whereby the severalsections may be removed and new ring-mounts of different sizes inserted,so as to adjust the cage-bars inwardly and take up the wear on the endsof the revolving beaters.

In the drawings ,1 designates the side frame of the machine, in which ismounted a rotatable shaft 2, having hammer or heater supports 3,pivotallycarrying beaters 4.

5 is the top or cover of the machine.

The material to be acted upon is fed into a ho per at'the forward endof'the machine and at-the lower end of which it is'acted upon by therevolving beaters, the material passing over a cage or screen,preferably composed of bars, until it is reduced to such size that itsparticles can pass through the openings therebetween.

The sides of the frame 1 are provided with curved grooves, from thebottom walls of which project lugs 1 for receiving the cagebars andring-mounts of different sizes, and in order toremove the cage andadjust it or put in new bars it is only necessary to-raise the hingedcover and withdraw the cage from its circular grooved seat. It is partof my present invention to group the cage-bars, so

that the cage may be inserted or removed in cured together by means of'arivet 7 passing throughthe heads thereof. The ring-mounts (designated bythe reference-numeral 8 and seated in the curved seats) are preferablyprovided with arcuate grooves 9 for the reception of the bars 6. Thecurved seats in the side frame 1 are of such radial depths as to receivethe groups of cage-bars and leave spaces above and below them, whichspaces will be determined by the positions it is desired that the caebars shall occupy with respect to the pat of rotation of the beaters.In actual practice it is intended to substitute different ring-mountshaving rooves struck from difierentcenters to provi e differentadjustments, so as to change the relative position of the several barswith relation to the beaters. The purpose of riveting a plurality ofbars together is to facilitate and quicken the' time in effecting achange in the adjustment of the radial distances of the cage from theaxes of rotation of the hammers or beaters; but it is obvious thatinstead of grouping a plurality of cage-bars together the bars may beseparately introduced.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is. I
